Enum W2nError 

pub enum W2nError {
    Words2Num(String),
    NotImplemented(String),
    Key(String),
}

The exception kinds this layer can produce, each carrying the exact message Python formats. The PyO3 binder maps each variant onto the matching Python exception class.

Variants

Words2Num(String)

words2num2.base.Words2NumError — a ValueError subclass.

NotImplemented(String)

NotImplementedError — raised by _resolve_lang.

Key(String)

KeyError — SCALE_SUFFIXES[scale_str] misses (e.g. "$5kn"). Python’s KeyError stringifies as repr(key), hence the odd quoting.

Implementations

impl W2nError

pub fn message(&self) -> String

The message text Python would carry (str(exc)).

Note KeyError is special-cased: str(KeyError("kn")) is "'kn'", not "kn".
